Does exactly what you think it does!
Ordered this as a replacement charger (my aunt lost the home charger to her Tom Tom). I think it's a little silly that the unit cannot charge through USB, but perhaps it is too much to ask. Anyways, the product works perfectly with my current Tom Tom and although I don't have the other non-American standard plugs to test, I'm sure the adapters work perfectly as well.

Not For Tom Tom Model 910
I purchased the charger based on Amazon's recommendation that others who purchased a Tom Tom 910 GPS, also purchased the charger. When I received the Tom Tom model 910, I found that a home charger was included with the GPS. When I returned from my European trip, I tried to return the unit to Amazon for credit but found that Amazon would not accept returns after 30 days. Now I'm stuck with an extra home charger.

Power Charger
Quality of item is poor. The connection between electrical cord and TomTom 910 are not good. Probably poor manufacturing or poor quality control. The electrical connection is broken by the slightest movement of either device causing the Tomtom not be be recharged.

USA-EUROPE
If you travel the U.S.A and Europe. This is your thing. Buy it.

mismailed TomTom One Charger
I love the Tom Tom One and very highly recommend it. However, the extra electrical charger I ordered does not adapt to the Tom tom One. As I am 3,000 miles away from home the electric charger is a disappointment. But the Tom Tom One is terriffic. It makes adjustments to my wrong turns and keeps me on track. I'm thinking seriously of buying a second one for my wife as soon as I get back home.
